Canary island data?
where can I find data on the canary islands? Data including the species and their distribution, bathymetric maps of the area to be able to tell sea level change over time this is to help with a dissertation, main topic is how climate change has affected island biogeographies.

Anyone know where I could obtain data for niche modelling? struggling to find some any ideas appreciated

You cand find data about species and distribution on this database:
Also, on this website you'll have a good bathymetric map (just select "Bathymetry" in the table of content)
I hope that these websites can help in your research.
Regards.

We are working on a climate change dataset for the canaries. To be released in autumn.

On sea-level change in the Canaries, in addition to the Rijsdijk et al (2014) paper that Mario directed you to, you might like to look at the Fernandez-Palacios et al paper that is in the special issue on island biogeography in Global Ecology and Biogeography (July 2016): http://onlinelibrary.wiley.com/doi/10.1111/geb.12320/full
On the species data, Daniel correctly pointed you to the Atlantis database as being the best source. However, you should be aware of its limitations and relative strengths. Here is an extract of something I published recently that looked at the quality of these data (taken from the supplementary material of http://onlinelibrary.wiley.com/doi/10.1111/geb.12425/full ):
"The Canary Islands are among the world’s botanically best-studied archipelagos, with European botanists surveying the islands frequently, and often intensively, since the beginning of the 18th century. The data used here originate from a long-term governmental initiative (BIOTAS/ATLANTIS). This initiative pulled together these sampling efforts over the centuries by gathering all available occurrence information for each species. More than 1,000,000 literature-based and herbarium records were digitized and geo-referenced on the Canary Islands, an area of less than 7500 km2 (Hortal et al., 2007). Following its success, the government initiative was extended to other Macaronesian archipelagos with the support of the EU project ATLANTICO – INTERREG III B (2000-2006).
The main initial aim of the BIOTAS/ATLANTIS project was supporting governmental decisions with empirical data; scientific interest arose later on. Despite the huge sampling effort, the database is not exhaustive enough to provide reliable presence–absence records for all species occurring on the Canary Islands. We thus agree with earlier publications that claim that the data provided are not suitable for direct analyses of spatial species richness patterns (Aranda & Lobo, 2011). Indeed, it is obvious that any richness map directly generated from the data reflects sampling intensity (Hortal et al., 2007).
The occurrence information reflects true occurrence records of species, but does have problems, particularly that for some taxa occurrence information at coarser resolution may have been downscaled to fit the 500x500m resolution of the data base. By integrating across the data collections of botanists across several decades of sampling, however, the data base provides very reliable information on the particular species in which botanists have been most interested for centuries – species endemic to the Canary Islands. Hortal et al. (2007) showed that richness patterns in the data are very biased by sampling intensity, quantifying sampling intensity by the number of occurrence records. Endemic species have more than twice the number of occurrence records, compared with non-endemic native species (mean number of records per species = 1750 for Canarian endemics, vs. 840 for non-endemic natives), indicating that the data base is most appropriate for characterizing the distributions of endemic species. Sampling has been primarily focused on locations where the endemics occur. From our personal observations over decades on the islands, we similarly perceive sampling to have been most intensive in less disturbed natural environments (often protected areas), and the distributions of endemic species, as mapped from the ATLANTIS database, to be realistic. We thus believe that the data provide good approximations of the distributions of endemic species, while many non-endemic species (particularly small, unattractive ruderal plants) are clearly under-sampled."

Hi.
You can visit the website of the project "Plinio XXI", developed by the Natural History Museum of Tenerife ("Museo de la Naturaleza y el Hombre") between 2011 and 2012. I worked in this project, which was based on a website with many information and photos about the Macaronesian islands and a digital library with a lot of papers and some books in pdf, many of them centred in the Canary Islands and the Cape Verdes. Please, visit this link:
Best regards, and good luck in your research.

WorldClim data error: GCCM MIROC-ES2L is missing?
Ryan Brodie
WorldClim (worldclim.org) has seemingly dropped the CMIP6 global coupled climate model MIROC-ES2L for all future climate scenarios. From what I understand, MIROC6 has replaced MIROC-ES2L without any notification or warning from WorldClim. MIROC6 and MIROC-ES2L provide different results and my current research relies on MIROC-ES2L data.
Is anyone else aware of this issue? Does anyone know of a data archive that houses MIROC-ES2L data from WorldClim? Specifically, I need bioclimatic, max temperature, min temperature, and precipitation data for SSP 245 and SSP 585 in 2050. I was trying to download 2030 data for a validation procedure, and that is when I noticed the problem.
Thank you very much for the assistance! I am hoping this is just a WorldClim database issue that can be fixed quickly.
How to download 1 km CMIP6 Climate Simulations?
Joshua A. Spiers
Hi Guys!
I usually download future climate data from Worldclim.org.
Their website says that "Data at 30-seconds spatial resolution is expected to be available by the end of March 2020", however, this has not materialized . . . https://www.worldclim.org/data/cmip6/cmip6climate.html
Does anyone know of alternative sources to download future data at this (1km) resolution?
Many thanks!

Running hierarchical partitioning with 10 variables: Is there an R package that works with 10 variables?
Sofia Kozidis
I have been using hier.part package and function in R and love it, but now I need to run hierarchical partitioning on a linear model but I have 10 variables. With more than 9 variables hier.part has rounding bias (see the (Olea, et al., 2010)).
Is there an alternative function in R to run hierarchical partitioning that works with 10 explanatory variables? I know it is a lot of explanatory variables for my candidate model, but I do not have any further ecological or statistical justification to remove any more explanatory variables before running best model selection.
I found the Stan125 package (https://github.com/Stan125/ghp) but it works off of hier.part so I do not know if I should use it.
Or would the adipart function from the vegan package accomplish the same results? Does hierarchical null model testing also show independent and joint effects?
Forgive me if I am not clear, I am fairly new to statistical analysis! Thank you for your time and help!
